Hi!
1. Okay, I see what you mean now. That is the elementor page, unrelated to the search. The plugin image options can only affect the images within the live results list (image 1). The page images are printed by elementor. You might have to adjust that somewhere in that plugin options.
2. Well I am sure it is possible, but then the filter needs to be corrected. Either some of the filter values are incorrect, or there is something wrong with the configuration. Without actually lookingat it I am not able to tell though.
